Micra brake caliper brackets

Hi, greetings from Finland!

We have a rally micra (MicRed raceteam) and we are upgrading our brakes. We have a problem, do you know the solution? Please help if you do!

We want to put 18mm disc to front brakes, so we need to get a bew caliper, we got that for the thicker disk but then the mountingpeace, bracket, does not fit.

We have the caliper for 1.4 micra, but in Finland there is nit for sale those mountingpeaces. Do you have them in UK?

Or other possible solutions for us...

Kindly asking, MicRed head of pr, Tanja
